After saying this, one of the young men flew directly toward the waterfall, appearing extremely menacing with a long knife in his hand as he soared through the air.
To reach the cave behind the waterfall, one must pass through the waterfall's water curtain. This man had just charged through the water curtain when he suddenly flew out from it.
It looked as if he flew out from the water curtain, but he fell directly into the pool. Only then did the people by the pool realize he had been struck out by someone.
He fell into the water, angering the other three. Two of them rushed directly toward the water curtain.
Similarly, their weapons appeared in their hands as they flew through the air. This time, they were mentally prepared, ensuring they wouldn't be ambushed. They almost simultaneously passed through the water curtain and entered the area behind it.
Bang!
With a loud crash, the two of them simultaneously flew out from the water curtain, falling into the water together.
